I AUTOMOBILE-JACK.

. of structure for furnishing 'power for vanous purposes when theautomobile is not being used for transportation.

To this end the invention comprises a structure upon which theautomobile may be moved by its own power and which .by such movement'ofthe automobile will causethe power wheels of the latter to be elevatedand the automobile to be supported in such elevated position with itsdriving wheels free from contact with any support, the driving end of.the automobile being then supported wholly by its axle or parts adjacentthereto, so that power may be transmitted from the wheels of theautomobile by suitable beltingfpre'ferably by a countershaft carried bythe structure forming the subject-matter of the present invention, sothat power may be 'taken from the countershaft for utilization. In orderthat the driving end of the automobile may be properly raised to carrythe wheels high enough, skids areprovided, one for each driving wheel,and elevating means for one end of each skid is also provided, so thatthe automobile may be backed upon the skids until ultimately the axle ofthe automobile is brought into contact with the stop member whichprevents further progressive movement of the automobile when thecontinued rotation of the wheels will cause longitudinal movement of theskids in a direction to depress the ends of the skids supporting thewheels, so that the automobile is lowered into supporting recesses,which because of their construction lock the automobile in the properposition for the taking off of the power from the drive wheels.

Th invention will be best understood from a consideration of thefollowing detailed description, taken in connection with theaccompanying drawings forming a part of this specification, with theunderstanding, however, that while the drawings illustrate Specificationof Letters Patent.

a practical form of the invention, the latteris susceptible of variousmodifications and practical embodiments differing in minor details fromthe showing of the drawings, and, therefore, the invention is notconfined to the exact construction shown, for it may be varied therefromtthile retaining the salient features of the invention.

In the drawings :-F1gure 1 is a plan view of the improved jack showing aportion of an automobile in dotted lines inoperative position. Fig. 2 isa side view of the structure of Fig. 1 also showing the automobile anddriving connections therefrom in dotted lines. Fig. 3 is a section onthe line 3-3 of Fig. 1, the automobile being omitted.

.Fig; t is a side view similar to that of Fig.

2, but showing the position of the automobile on having been backed uponthe skids and prior to being lowered on the su ports, the automobilebeing shownin dotted lines. Fig. 5 is a view similar to Fig. 4 butshowing the position of the parts as the automobile comes to rest on thesupports, the automobile being shown in dotted lines. Fig. 6 is asection on the line 6-6 of Fig. 4, distant parts being omitted. Fig. 7is a section on the line 7-7 of Fig. 1.

Referring to the drawings, there is shown a frame composedoflongitudinal members 1 joined together in spaced parallel relation bycross pieces 2, it beingcustomary to make these parts of wood, but itwill be understood that they may be made of metal instead of wood, andthe shape and relation of the parts may be varied within limitsdepending upon the particular use :to which the structure s to be put.

About midway'of' the longitudinal beams 1 are blocks 3' upstanding fromthe tops of the beams 1, and these blocks beingmade ofwood may besecured to the beams l by straps L, 5, respectively, the strap 5 beingan angle strip confining an angle block 6 which will act to resist blowstending to loosen or overturn the standards 3 in the direction towardthe blocks 6. Each block or standard 3 is formed on the upper surfacewith a notch 7 and at one side of the notch with'an upstanding member 8,which, as will hereinafter appear, is designed to receive the impact ofthe axle of the automobile to prevent movement of the latter beyondapredetermined point. The blocks or standards 3 may be furtherstrengthened by brace rods}; extending toward the center I orti on. agan intermediate to} strengthen and 2 i a lo g u a ly may extend to-theendof the framework received,i:fand thisthe -outer faces-A; o ea lheremaitqr:

Thisconstruction is," however, not mandatory. IAs soon as theaxle 28 of the automobile c 0mcs int o'engagement with the nbutments 8further progressive movement of the auto- I mobile is arrested,but thewheels 29 may still continue to rotatewith the result that the skidswhere engaged by thc'wheels now receivea' more powerful im ulse thanwhen the automobile is being baclted up the skids, with the result thatthe shafts 17 and 18 are -turncd to carry the cranks 20 in a directionaway'from the stop blocks'26, and as these blocks may be located, sothat the crank-s rest against them with an inclination to thevertical,;considering the device as resting on ahorizontal"surface,these cranks must be moved as througha rising arc with the then upperends of the skids participating in such rising movement before thecranks {can reach thehighest point of their travel, after whiehtheywillmove through a lowering are, thus causing the axle 28 of. the automobileto drop until finally it rests against the upper ends of the blocks 3with the truss rod or rods 31 usually present on the power aide of anautomobilein the notches 7.- The -relative position of the automobile tothe deice when the power axle of the machine is resting on thesuplporting blocks 3 is shown in Fig. ,5. Whenthis positionh'as .beenassumed, the skids 22 may continue their movement toward the lowestposition, either, by gravityo'r byanappro riat'e force applied to thesquared ends 21 o the cranks 20, until -,ultin'iately the parts assumeabout the posi-' tion shown in Fi with the skids out of 29;:Now,fsuitablebel ts 32 may be the tires of carried from he automobiledrive wheels to the respectivepulle'ysM and in order that these belts'may readily applied and yet engage the wheeledtires'. and 'ulleys withsulficient grip, each belt 32 may e controlled by a belt tlghtener cornrising a lever"33 carrying at one end are ler 34' to engagethelrespective-belt 32'and. at an inter-- mediate point provided witha-pivot 35 carried by a journal bearing 36 or other sup-' priute point.The belt' tightener lever 33 {is shown in the drawings as normally con-1 (rolled lav a spring 37eonnected at one end to therespective beam 1and at the other end to that end of the lever .33 remote from the roller34.

power available for any purpose desired automobile is being utilized forother pinposes than thepropulsion of the automo ile.

Itwill be observed that the automobile raises itself to the appropriateheight by way of the skids 22 and then by a continuation of the tractivemovement of the power wheels the skids are caused to gradually lower theautomobile to its sustaining ele-' 5 vated support without subjectingthe'automobile structure to any jars which might occur were the vehicleallowed to gravitate 4 freely on to an elevated support from agreaterelevation to which it is lifted in 40'0rder to bring it intooverstanding relation to the said elevated support, in order that itmight be' lowered thereonto.

\V-hen' the automobile is to be removed from the jack, a wrench or leverapplied to the squared ends of the cranks 20 may be manipulated toelevate the ends of the. skids carried by said cranks until thetllliUll'lObllC is' free from the blocks 3, and then the automobile maybe moved down the skids until free from the jack;
